Round Swirl Cupcake Frosting- What Is Your Go To Tip Size?

I'm just starting out and my first project is confetti cupcakes for my girl's birthday party Saturday. I got inspired by a Pinterest image. I was originally trying to go for a bakery style big swirl design but now I wonder if I went a little TOO big with the Ateco 809! I feel like the cupcake is dwarfed by the icing :/. Then I realized I want the cake to icing ratio higher as well.

Did a little digging and I'm finding I'm gravitating to ones with a half inch opening. I'm not sure if this will be too small?

is there a cimprehensive comparison image out there to help me decide? I'd like to see results from say the Ateco 806 and up for example.

under the heading of 'any thoughts appreciated' i think you should buy several and compare in person -- there may be some charts but what i mean is you can pipe different amounts of icing by the pressure you apply so the exact size of the tube is not the be all end all -- i have some tubes i totally love and some i never ever ever use and it's all personal no method to it -- so start you a collection is my 'any thought' for you --

I have a very light squeeze on the pastry bag (not a lot of hand strength), so big tips are great for me. I worked with people who could squeeze out that swirl with a 4 I think (Popeye arms). So K8's advice is spot on. Tips are cheap. Buy a few and see what works best for you.
